DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In order to make the technical features, the propose and the technical effect of the present application more clearly, the specific implemental means of the present application will now be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1-8, an electronic cigarette is constructed in the present application, which comprises an atomizer 1, and a first electrode 2 and a second electrode 3 which are inserted in an end portion of the atomizer 1. The atomizer 1 is further provided therein with an atomizing element 5 for atomizing tobacco tar, and a first lead wire 51 and second lead wire 52 which are electrically connected to the atomizing element 5. The second electrode 3 has an extension part 31 that extends into the interior of the atomizer 1. The second lead wire 52 is electrically connected to the extension part 31, while the first lead wire 51 is electrically connected to the first electrode 2. At least one first through-hole 32 is defined on a side face of the extension part 31.

A first air channel 35 is defined in the interior of the second electrode 3. The first through-hole 32, the first air channel 35 and the interior of the atomizer 1 are communicated with each other to form a passage allowing airflow to pass through.

It could be understood that, the first lead wire 51 and the second lead wire 52 are respectively the positive wire and the negative wire led from the atomizing element 5.

The atomizing element 5 includes heating wires or an ultrasonic oscillator.

In the present application, an extension part 31 extending into the interior of the atomizer 1 is provided, and at least one first through-hole 32 is defined on a side face of the extension part 31. In this way, since the first through-hole 32 for ventilation is defined on the side face of the extension part 31, it is not limited to use a soldering method to connect the second lead wire 52 to the second electrode 3 in this case, and a clogging of the ventilation hole is prevented from occurring even though the second lead wire 52 is connected to the second electrode 3 by means of soldering.

An insulating ring 34 is sleeved between the first electrode 2 and the second electrode 3. A projection 21 having a shape matching with an outer shape of the insulating ring 34 is projected inwardly from the first electrode 2. The projection 21 is sleeved on the outside of the insulating ring 34, while the insulating ring 34 is further sleeved on the outside of the second electrode 3. It could be understood that, the projection 21 and the insulating ring 34 are connected to each other by an interference fit, while the second electrode 3 and the insulating ring are also connected to each other by an interference fit.

A flange 33 is formed on one end of the second electrode 3 along an axial direction of the second electrode, and the end of the second electrode is away from the extension part 31. The flange 33 is abutted against an end portion of one end of the insulating ring 34, and the end of the insulating ring is away from the extension part 31.

It is possible for the second lead wire 52 to be electrically connected to the second electrode 3 in the following ways:

Embodiment One

As shown in FIGS. 5-8, a clamping element 6 is sleeved on an end portion of the extension part 31. The second lead wire 52 is clamped between the extension part 31 and the clamping element 6, and is further electrically connected to the second electrode 3.

A blind hole is axially defined on the end portion of the extension part 31. The clamping element 6 is an element having an “E”-shaped axial section matching with the blind hole. Or, the first air channel 35 runs through two ends of the second electrode 3, and a second through-hole communicated with the first air channel 35 runs through the clamping element 6 along an axial direction of the clamping element. The clamping element 6 is an element having an “E”-shaped axial section, and the second through-hole axially runs through the middle of the “E”-shaped element (as shown in FIG. 8 specifically).

At this time, the first lead wire 51 is clamped between the insulating ring 34 and the first electrode 2. The clamping element 6 is made of silicone or other kinds of soft materials. It could be understood that, the second lead wire 52 is fastened to the extension part 31 via the “E”-shaped clamping element 6. And the clamping element 6 is sleeved on the extension part 31 by an interference fit.

It could be understood that, it is possible for the axial section of the clamping element 6 to be designed in shape of a “T”. Or, a second through-hole communicated with the first air channel 35 is defined on an end face of the clamping element 6, and the axial section of the clamping element 6 is in shape of a “T” with a second through-hole running therethrough in the middle.

It could be understood that, it is possible for the clamping element 6 to be in various shapes, as long as the second lead wire 52 may fixedly clamped at the end portion of the extension part 31 via the clamping element 6.

Embodiment Two

As shown in FIGS. 1-4, the second lead wire 52 is connected to the extension part 31 by means of soldering.

Implementing Method One: As shown in FIGS. 1-2, an end face of the extension part 31 is closed, and the second lead wire 52 is soldered to the end face of the extension part 31. At this time, since the second lead wire 52 is soldered to the end face of the extension part 31, and the first through-hole 32 is defined on a side face of the extension part 31, a clogging of the ventilation hole will not occur since the soldering tin is at a large distance from the first through-hole 32. Preferably, in this case, there are two first through-holes 32.

Implementing Method Two: As shown in FIGS. 3-4, the first air channel 35 runs through two ends of the second electrode 3. The second lead wire 52 is soldered on the side face of the extension part 31, and the second lead wire 52 and the first through-hole 32 are staggered from each other. In this case, a clogging of the ventilation hole will not occur, since the second lead wire 52 and the first through-hole 32 are staggered from each other.

Preferably, there is only one through-hole 32 in this case. Since two ends of the first air channel 35 are communicated with each other at this time, it is possible to guarantee the airflow volume flowing through the second electrode 3.

In the two implementing methods of embodiment two, the first lead wire 51 is soldered on the first electrode 2 in each case.

In the two embodiments described above, it is possible for the first through-hole 32 to be in shape of a circle, an ellipse, or a polygon. To guarantee the airflow volume, an area of each of the first through-holes 32 ranges from 2 mm² to 20 mm². Besides, when the first air channel 35 runs through two ends of the second electrode 3, an area of a through-hole running through the first air channel 35 in the axial direction also ranges from 2 mm² to 20 mm².

A length of a portion of the extension part 31 projecting beyond the insulating ring 34 ranges from 5 mm to 10 mm. In this way, a length of a portion of the extension part 31 of the second electrode 3 that is inserting into the atomizer 1 will not be too long, such that the first lead wire 51 and the second electrode 3 will not contacted with each other by misoperation, and that a short will not be occurred between the first lead wire 51 and the second electrode 3.

In conclusion, the first through-hole 32 is defined on the side face of the extension part 31 (the extension part 31 is inserted into the atomizer 1) of the second electrode 3, in such a way that the second wire lead 52 may be connected to the second electrode 3 in a various ways, and a clogging phenomenon will be prevented from occurring when the second lead wire 52 is connected to the second electrode 3 by means of soldering.
